Globalization has led to increased interdependence between nations through the free movement of goods, services, capital and labor. Key factors driving globalization include reductions in transportation and communication costs as well as technological advancements. While globalization offers economic opportunities through expanded trade and access to new markets, it also poses challenges such as threats to local industries and concerns over the impacts on cultural identity. International organizations like the WTO, IMF and World Bank facilitate globalization through policies promoting open trade, financial cooperation and development assistance.
